Check out the image above to see my current output.

<template>
    <column-chart lable="value" :min="0" :refresh="60" height="400px" 
     xtitle="City" :data="series" :library="values"></column-chart>
<template>

Included below is the script I am utilizing in Vue.js

<script>
   data(){
        return{
            values: {
                borderWidth: 10,
                dataLabels: {
                    enabled: true
                }
            }
        }
    },
</script>

Answer №1

Consider incorporating

the attribute "label="Value"

into your column-chart component,

like this:

<column-chart :min="0" :refresh="60" height="400px" xtitle="City" 
:data="series" label="Value"></column-chart>

Although it's more of a workaround, as there isn't a straightforward method to achieve this.

Utilizing the pluginservice:

Chart.pluginService.register({
    beforeRender: function(chart) {
        if (chart.config.options.showAllTooltips) {
            chart.pluginTooltips = [];
            chart.config.data.datasets.forEach(function(dataset, i) {
                chart.getDatasetMeta(i).data.forEach(function(sector, j) {
                    chart.pluginTooltips.push(new Chart.Tooltip({
                        _chart: chart.chart,
                        _chartInstance: chart,
                        _data: chart.data,
                        _options: chart.options.tooltips,
                        _active: [sector]
                    }, chart));
                });
            }); // disable normal tooltips 
            chart.options.tooltips.enabled = false;
        }
    },
    afterDraw: function(chart, easing) {
        if (chart.config.options.showAllTooltips) {
            // prevent animation of permanent tooltips until animation runs at least once
            if (!chart.allTooltipsOnce) {
                if (easing !== 1) return;
                chart.allTooltipsOnce = true;
            }
            chart.options.tooltips.enabled = true;
            Chart.helpers.each(chart.pluginTooltips, function(tooltip) {
                tooltip.initialize();
                tooltip.update(); // unnecessary since we are not animating tooltips 
                tooltip.pivot();
                tooltip.transition(easing).draw();
            });
            chart.options.tooltips.enabled = false;
        }
    }

Add 

options: { showAllTooltips: true, }
to the chart configuration.
